Question about BCI2000-OpenBCI: filters.

Post by lisapelagalli » 15 Feb 2019, 09:46

Hi,
I'm using OpenBCI and BCI2000 version 3 for a P3Speller Task. I've already modified the OpenBCIADC.h and OpenBCIADC.cpp to set the correct configurations like SampleBlockSize,sampling rate, sourceChGain and so on. Then I modified the SourceFilter.cpp to set highpass-lowpass filters at 0.1 Hz-60 Hz and the Notch filter at 50 Hz. When I take data from BCI2000 and I analyze them in Matlab, I notice that there is not the correct filtering I wanted to set.
What should I do?

Regards,
Lisa

Hi,

you don't set configuration parameters in source files but in the Operator module's Parameter configuration GUI.
Or you write them into a parameter file and load that at startup.

HTH,
Jürgen
